Title: Superconducting device
Inventor: HATANO MUTSUKO
IPC: H01L39/22
Filed: 1987-06-15
Abstract: PURPOSE:To facilitate controlling the characteristics with a minute current by a method wherein a superconducting electrode made of oxide superconductor and a control electrode which controls the status of a depletion layer in the superconducting electrode are provided. CONSTITUTION:A Schottky barrier is employed as a means to control a superconducting current. An oxide superconductor thin film of a K2NiF4 type structure or a provskite type crystal structure is formed on a substrate 4 made of MgO by a sputtering method and processed to form a superconducting electrode 1. Then normal-conducting metal selected among Al, Cu, Ni-Cr, Sn and In is applied to the surface of the superconducting electrode 1 by a resistance heating evaporation method and the evaporated metal is processed by a dry- etching method to form a control electrode 2. Therefore, along with the increase of a voltage applied to the control electrode 2, the width of a depletion layer formed in the superconducting electrode 1 is consecutively widened and the applied critical superconducting current is consecutively reduced. With this constitution, the superconducting current applied to both the ends of the superconductor can be modulated.

Title: Wide-field-angle liquid crystal display device
Inventor: RYU ZAICHIN
IPC: G02F1/1343
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To obtain the device which has a wide field angle and can prevent a light leak by diversifying the long-axis directions of liquid crystal molecules by making good use of a fringe field at the time of electric field application. SOLUTION: The long-axis directions of liquid crystal molecules are diversified by making good use of the fringe field at the time of electric field application. Of this device, part of the ITO electrode 4 of the upper substrate 2 is open. When no electric field is applied, the liquid crystal modules 3 are arrayed continuously at right angles to the upper and lower substrates 1 and 2, so a Bragg state is developed similarly to no opening of the electrode 4. When an electric field is applied, an electric field nearby the opening of the electrode 4 is not produced completely at right angles to the substrates 1 and 2. Here, the array direction of the liquid crystal molecules 3 is to become perpendicular to the direction of the electric field since the liquid crystal has negative dielectric anisotropy.  The long axes of liquid crystal molecules 3 nearby the opening part are twisted slanting to the surfaces of the upper and lower substrates 1 and 2 because of the fringe field.

Title: Rectifying circuit using field effect transistor
Inventor: MASAMOTO KAZUHIKO
IPC: H02M3/28
Filed: 1990-06-08
Abstract: PURPOSE:To reduce the driving loss of a field effect transistor by applying the driving voltage of a field effect transistor after half-wave rectification, and also equipping it with a gate discharge circuit, which discharges the charge accumulated in a gate capacity. CONSTITUTION:When a switch element 1 is turned on, the output voltage of the driving winding of a transformer 4 turns on a field effect transistor (FET) 2 via diodes 12 and 10 and resistance 14. When the switch element 1 is turned on, by the charge accumulated in the gate capacity Cgs of the FET2, the base current of a transistor 8 flows, so it shorts the gate with the source quickly and turns it off. On the other hand, in an FET3, when the switching element 1 is on, the charge of a gate capacity, which was charge immediately before it when the switching element 1 was off, is discharged due to the quick short by a transistor 9 and, so it is turned off quickly. Next, when the switch element 1 is turned off, by the voltage induced in the driving winding of a choke coil 6, the FET 3 is turned on.
